@koehntopp Hi koehntopp! At this time, Bitwarden can only *decrypt* your vault with passkeys that support this, otherwise, it will continue to use your master password for decryption. You can read more about this in the blog article below and know that we will continue to work on this as the technology and adoption improves! https://bitwarden.com/blog/prf-webauthn-and-its-role-in-passkeys/
